Do You Know: After Taking the Medicine Changbai, I Went Crazy?

[Do you know the same person] [No blood relation + fake brother and sister + double purity] As the third daughter of the Sheng Mansion, Sheng Qinglan was raised at the knees of her legitimate mother since she was a child. She was close and harmonious with her legitimate brother Sheng Changbai, which made Ru Lan secretly jealous all year round. I thought my life would be stable and smooth, but after Mo Lan Fengguang married into the Earl of Yongchang, Lin Xiaoniang, who was desperate, revealed a shocking secret in public in order to survive. She is not a descendant of the Sheng family at all, she is just an orphan girl from a farmer who was wrongly adopted back then! Overnight, she was reduced from a delicate young lady in the Sheng Mansion to a rootless adopted daughter. Sheng Hong even ruthlessly promised her to a poor scholar from a poor family, and the whole thing was done carelessly. In despair, Sheng Qinglan found the married Mo Lan and borrowed a decoction that could distract people's minds, planning to make a desperate bet for herself. After a night of absurdity, Sheng Changbai, who was sober the next day, spoke coldly: I will not marry you. But just when the entire Sheng family was forcing her to get married, Sheng Changbai, who had always abided by ethics, spoke in public, shattering everyone's plans: "There is no need to force her, we are already committed to each other, I will marry her." From then on, the orphan girl from a peasant family counterattacked and rose to power, married into the Sheng Mansion, and killed the queen's wife all the way! Reading Guide 1.
